I'm currently planning a complete refurb of our property: the EIB/KNX equipment looks great, not only from functional point of view, but style as well, esp. the integrated thermostat + controllers. Only problem is that all of the manufacturers (theben, gira, jung, merten, etc) seem to be german - is this kind of technology (a) not generally used in the UK at all, or (b) used in the UK, but mostly commercial and not residential. Any experiences with it - main complication seems to be in the initial commissioning, perhaps requiring an expert (even though I am myself tech savy MIET eng). We're rewiring the entire property, so I get a chance to start from scratch.
